Definition

Antoine Micheau & Muhammad A. Javaid

Choroidal branch to fourth ventricle of posterior inferior cerebellar artery:

The posterior inferior cerebellar artery (PICA) gives choroidal branches to the tela choroidea and choroid plexus of the fourth ventricle. These branches provide the majority of the arterial supply to the choroid plexus associated with the roof and median opening (foramen of Magendie) of the fourth ventricle. Their precise origin along the PICA may vary because of the artery's variable branching pattern.
